Installation Blocked Error
Are you getting and "Installation Blocked" error when trying to update your Jailbroken Fire TV Stick programs?
Just like this screenshot below
It's an a TV error, its just an option you need to enable before updating.
At your Amazon home screen
Scroll to settings
Scroll to Device
Select Developers Option
You basically just want to have App from unknown sources turned on, so that you can install and/or update your programs.
Once you have it enable, reopen the program and you should be promoted an update.
